In fact concrete allows energy to flow through it roughly 60x faster than insulation.
Tilt up concrete wall r value.
The standard r value of ready mix concrete used in the tilt up industry including the air film is 1 49 for an 8 inch wall panel.
However insulation can be added easily to any tilt up panel.
For instance if you have a material with an r value of 12 attached to another material with an r value of 3 then both materials combined have an r value of 15.
Astm c1363 effective r value testing typical physical properties wall assembly description eff.
You will notice in the findings shown in the isothermal analysis that the thermomass wall panel has a material r value of r 11 49.
What s the r value of a tilt up concrete wall the simple answer to the question is solid tilt up concrete panels have very little r value 0 08per inch.
By doubling the thickness of the wall to 16 inches the r value only increases by 0 50.
But like all concrete systems tilt up offers high thermal mass and airtight construction.
However since it s easy to add insulation to any tilt up panel this number can rise substantially.
As we said before the r value measures the thermal resistance of a material.
The 3 most common insulation methods for tilt up concrete construction.
As building codes require greater energy efficiency the thickness of insulation increases.
Walls can range from r values of about 2 for uninsulated panels up to about 32 for walls containing thicker layers of insulation.
